CC306 AFR 195cc eliminator heads great MPG CC306 and AFR 195cc eliminator heads better mpg than stock form.
Before my rebuild I was getting maybe 10mpg city/ 15-17 hwy.
I went on a road trip this weekend, first one since the build up, and covered over 500 miles averaging 22.34 MPG@ 72mph through an A4 with yank ss3600. Honestly I was expecting 18-20 mpg hwy. In town I'm pulling 13-15 mpg which is decent. For those who still wonder about the cc306 being streetable, this cam is great. Ya it's an old grind, but it's solid! I still get a slight cam surge but u get used to it quick. My passengers don't notice the surge but I do. The heads are a bit overkill for a 355, but again, no drivability issues. Who says you can't have your cake and eat it too. Haven't made it to a dyno yet, but I'm expecting 420-430 to the wheels. Maybe after the dyno I can even get a few more miles per gallon.

I've heard alot if bad things about AFR but that's from mainly guys with AI heads. With this being my first set if after market heads, I say they're the best company out. Lol.

This build was on the books for at least a year. I must have changed my mind a million times. Before this car I was a motorcycle guy. This was my wifes car that I kinda borrowed and never gave back. I read a few books and Internet post, asked a few questions, bought a few tools and jumped into this thing. I didn't know what to expect from a cc306 nor do I no what to look for in a custom grind. I'm not a master mechanic like most guys on here nor have I been doing this long. Just a guy who found a hobby and fell in love.

From the research I've done, I agree. Myself not knowing which way to go, spent hours on the phone the past year with different companies and for a street cylinder head with nitrous AFR 195's got my vote. I have a wer kit I picked up but it's just collecting dust at this point.

But I compared numbers between off the shelf heads and these had by far the best flow numbers. I prefer a new set of heads because I wouldn't like alot of down time :/

lncboytre_d , which je pistons did you go with to get 11.4:1? I'm pretty much looking to do the same build, a 355 but i'm shooting for all forged rotating assembly w/hbeam rods. Most likely from scat. Its encouraging to hear such good MPG's with 400+ ponies

AMS Racing out of Shreveport Louisiana put my bottom end together, I'll have to find my receipt and get the part number for you. I told him the setup I had up top and that was the CR he said I would be at.

Very nice I wish I got that. No offense but I think your hp numbers are a bit of a stretch, trust me these autos with big stalls eat power like you would not believe on the dyno. The one time I put down 362rwhp/370rwtq unlocked with a setup that is pretty equal to you power wise and went straight to the track and did 11.88 at 114.3 in the heat so obviously the numbers dont really match up. However, you will easily be running 11's with your setup and that is all that matters!
